For going through Aspen, CO, that indicates you believe you will be using Highway 82 east of Aspen. You can't take your trailer on that stretch of highway.
This, from the
CDOT page specific to Independence Pass: "Absolutely no vehicles over 35 feet in length (this includes a vehicle and trailer that, together, exceed 35 feet) may use the Pass at any time. These pass restrictions lie between MP 42 (Aspen side) and MP 84.2 (Leadville/Twin Lakes side, about one mile west of the junction with US 24)."
I had a smaller trailer, and didn't use the pass, due to a very narrow stretch on the west side of the pass. Don't plan on using Hwy 82 east of Aspen.
